The test method for abrasion (ISO 4649 / DIN 53516) is actually quite simple. Abrasion resistance is measured by moving a test piece of rubber across the surface of an abrasive sheet mounted on a revolving drum. It is expressed as volume loss in cubic millimeters, for instance, 150 mm.

ISO 4649:2017 specifies two methods for the determination of the abrasion resistance of rubber. Method ISO 4649, in general, involves rubbing the specimen on a specified grade of abrasive. Then evaluate the abrasion degree of the specimen by the change in the specimen.

*Please Note: The information outlined above is to be used as reference for ASTM D5963 Standard Test Method for Rubber Property - Abrasion Resistance (Rotary Drum Abrader) and ISO 4649 Rubber, vulcanized or thermoplastic -- Determination of abrasion resistance using a rotating cylindrical drum device. Please refer to the appropriate standards agency for full details and the most current revision.
